Re: Corsair CX400W 5vsb goes into safety loop
The layers are so thin and close together that they aren't very visible in a picture like that. I've seen the small value high voltage caps cracked open (huge case sizes like 4040 just for the...

Re: best cheap/free scores 1.1
There might be a setting to change that. If I remember right, it's in the BIOS on AMD systems, so HP might have removed it. 2GB of video RAM is ridiculous for a computer like that, especially when it...

Re: Post your system.......
I remember that, and this laptop was patched pretty quickly (as expected for a business laptop).
Another thing is how annoying the Lenovo Vantage software is. It's nice to get updates if there's a...

Re: Post your system.......
I'm surprised by how low the prices are on gaming laptops now. That one actually looks nice. I get about the same battery life on my current laptop with a 90Whr battery.
I don't think I posted my...

Re: DIY amp for speakers
Figures 13 and 14 in that datasheet show the maximum output power over the supply voltage range. I would guess that you'll get about 10W per channel into 6 ohms.
Power consumption will vary with...

Re: MGX7520 onboard graphics problem
I don't think 25 ohms would show up in temperature measurements.
Can you see what that cap connects to? The CPU takes 2.9V and 3.3V, and I would guess that the Cx5520 runs off the same 3.3V...

Enabling Intel Platform Trust Technology will run some kind of software emulation of the TPM for the few people who actually want Windows 11. I would expect it to be enabled by default on a current...

Re: new apple studio display uses capxon caps
Apple already has the cult who thinks it's cool to constantly buy new stuff (and create e-waste as a consequence), so there isn't any need to force products to fail. It's just a company being cheap...

Re: new apple studio display uses capxon caps
CapXon is unavoidable. I can only hope that their quality has improved, but I doubt it.
On top of that, the design of this monitor is insane. What are they doing with a full iPhone SoC and such a...

Re: best cheap/free scores 1.1
That HP/Compaq 7550 isn't a Trinitron. I saw a lot of those at the schools I went to. I remember some of them having a really screwed up picture when they were new (like shaking horizontally), but...

Re: Best video card for 2D?
Video card prices went nuts over the last couple of years (for reasons that might be best discussed in the VIP forum), so I don't think you'll find anything under $100. Right now, I see people buying...

Re: Post your worthless and/or pointless repairs
I get a little bass from it, but I think there's a dip in the response just above the port tuning frequency. I think there's still a little peak around 1kHz with the current component values (47µF...
